The role of learners’ epistemic beliefs in an online Community of Inquiry     

Kun Huang  Victor Law  Sang Joon Lee 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(4):1882-1895

The Community of Inquiry (CoI) model provides a lens to examine online learning through three elements: teaching presence (the design and facilitation of learning experiences), social presence (the extent to which learners project themselves as real people) and cognitive presence (the extent to which learners are able to construct meaning through inquiry and reflection activities). While research to date has established the importance of these essential presences in online learning environments, recent research on the CoI model calls for the need to explore the role of learner characteristics. The current study responded to the call by examining the role of learners’ epistemic beliefs (EB) (ie, individuals’ fundamental beliefs about the nature of knowledge and knowing) in an online CoI. Multiple linear regressions analyses revealed that EB moderated the relationship between learners’ perceived teaching presence and cognitive presences. Future studies on CoI should take learners’ epistemic beliefs into consideration, especially in the case of low teaching presences. Theoretical and practical implications for designing and investigating online learning are discussed.  相似文献   

高斯光束微圆孔衍射变换的数值仿真实验     

常山  毛杰健  桑志文  吴志伟 《实验技术与管理》2011,28(1):80-83,87

高斯光束的微圆孔衍射变换在微光学、激光技术以及微光机电技术中发挥着基础性作用,通过数值计算模拟实验可以对它进行研究与探索。由菲涅尔-基尔霍夫衍射公式得到单色点源平面屏衍射的积分式,类推得到高斯光束圆孔衍射的积分式,并给出这一积分式的一种数值计算方法。利用Matlab软件进行了高斯光束微圆孔衍射变换的数值仿真实验研究,这有助于激光束的实际衍射实验及其测控理论与技术的研究以及光学教学的改革。  相似文献   

从岳阳海关衰兴看经济开放     

黎桑  李望生 《岳阳职业技术学院学报》2011,26(5):33-35

岳阳自古不仅为兵家必争,而且是税关重地。从1899年岳州正式开埠到1939年岳州关全部关闭,近40年时间,一直由洋人统治。闭关了50年后,1988年,岳阳海关又重新建立。新的岳阳海关是岳阳国民经济发展到一定程度,进出口贸易达到一定水平后重建的。本文站在历史的角度,从岳阳海关的衰败到兴盛,反映出中国自改革开放以来主权的不断强大和经济的迅猛发展。  相似文献   

Browsing software of the Visible Korean data used for teaching sectional anatomy     

Shin DS  Chung MS  Park HS  Park JS  Hwang SB 《Anatomical sciences education》2011,4(6):327-332

The interpretation of computed tomographs (CTs) and magnetic resonance images (MRIs) to diagnose clinical conditions requires basic knowledge of sectional anatomy. Sectional anatomy has traditionally been taught using sectioned cadavers, atlases, and/or computer software. The computer software commonly used for this subject is practical and efficient for students but could be more advanced. The objective of this research was to present browsing software developed from the Visible Korean images that can be used for teaching sectional anatomy. One thousand seven hundred and two sets of MRIs, CTs, and sectioned images (intervals, one millimeter) of a whole male cadaver were prepared. Over 900 structures in the sectioned images were outlined and then filled with different colors to elaborate each structure. Software was developed where four corresponding images could be displayed simultaneously; in addition, the structures in the image data could be readily recognized with the aid of the color-filled outlines. The software, distributed free of charge, could be a valuable tool to teach medical students. For example, sectional anatomy could be taught by showing the sectioned images with real color and high resolution. Students could then review the lecture by using the sectioned and color-filled images on their own computers. Students could also be evaluated using the same software. Furthermore, other investigators would be able to replace the images for more comprehensive sectional anatomy.  相似文献

图书馆服务制度建设任务分析：基于关键事件分析法   总被引：2，自引：0，他引：2  

李桂华  彭文凤  郭桑 《中国图书馆学报》2011,37(4)

了解用户在接受图书馆服务过程中发生的“关键事件”,可以发现影响用户服务质量的症结所在,进而为高效的服务管理制度设计和安排提供依据。应用关键事件法,通过开放性问卷调查,收集了501名用户接收图书馆服务中的满意和不满意事件,从管理、行为、态度、资源四个主题范畴,展开对各主题的案例分类。分析结果表明,关键事件调查反映了图书馆服务管理中可能出现的各种服务质量问题,而且这些问题所映射的管理环节和管理因素之分布呈现集中性。基于此,提出图书馆服务制度建设中的核心岗位、关键流程和重点制度,并阐述了针对这些服务环节的制度建设任务。图1。表8。参考文献11。  相似文献   

Evaluation of Korean information infrastructure policy 2000–2010: Focusing on broadband ecosystem change     

Dong-Hee Shin  Sang Hee KweonAuthor vitae 《Government Information Quarterly》2011,28(3):374-387

South Korea has been very active in broadband development for the last decade, which has made major strides in its development. This study evaluates the evolution of Korea's broadband development from the year 2000 to the present day. Historic and archival data related to Korean broadband projects are reviewed in this paper, drawing on broadband ecosystem as a framework for assessment. The purpose of this study is to provide insight into challenges and create a prospectus by offering a socio-technical analysis of broadband development. This will involve the in-depth investigation of the social dynamics, political discourse, and technological choices inherent in the design and development of the next generation of networks. Despite active investment and proactive drive, uncertainty still remains surrounding the evolution of broadband and what impact it may have on the new broadband milieu in Korea. This study will offer an effective adoption/diffusion strategy as well as a viable information policy model for more advanced infrastructure in other countries.  相似文献
